Title: Machine for Profiling Annular Workpieces by Rolling
IPC: B21H1/16
Filed: 1968-04-05
Abstract: 1,192,839. Rolling rings. ROTARY PROFILE ANSTALT. 5 April, 1968 [19 April, 1967], No. 16522/68. Heading B3M. A machine for rolling annular workpieces includes at least two rolls defining an axially extending convergent throat, a workpiece which loosely surrounds a mandrel being rolled as it advances along the throat. The mandrel rolls by its ends on one roll, and urges the workpiece against either another roll or a control ring containing the workpiece. In a three-roll arrangement, Fig. 1, a workpiece 13 is contained within a control ring 14 and surrounds a mandrel 15. Rotation of rolls 10 and 11 causes feeding of the workpiece axially of the rolls due to the cooperation of the ring 14 within helical grooves in the rolls. The roll 12 is plain and can be idle or driven. A head 18 on one end of the mandrel engages the grooves to feed the mandrel with the workpiece. The rolls can have axes which converge slightly or have increasing diameters along the throat length. Alternatively the roll 12 can be moved towards the other rolls driving profiling. In a two-roll arrangement, only one grooved roll, 10 or 11 is used. The ring is moved across the nip of the rolls, due to a difference in the rolls' speeds, in addition to its axial movement. An alternative arrangement, Fig. 7, includes an inner grooved roll 40 positioned concentrically within a hollow roll 42, the rolls defining a converging annular throat. Several workpiecemandrel assemblies are rolled simultaneously. The control ring for a workpiece may be dispensed with. By arranging for the final position of the throat to be of constant size, a burnishing action can be applied to workpieces.

Filed: 1945-06-30
Abstract: 603,241. Power-meters. TURNER, L. B., and BUCKINGHAM, J. June 30, 1945, No. 16701. [Class 37] An ultra-high-frequency wattmeter comprises a section of transmission line having mounted thereon two detectors a quarter-wavelength apart which are connected to an indicating instrument whereby the latter indicates a function of the field strength in the line at the points where the detectors are located. In a preferred arrangement, square law detectors in the form of thermo-couples 5, 6 enclosed in detector-probes 3a, 4a and positioned a quarterwavelength apart in a wave-guide 1 adapted for insertion in an ultra-high-frequency line, each develop an E.M.F. proportional to the square of the field strength at their points of location. A galvanometer G in series with thermo-couples 5, 6 and therefore deflected in proportion to the sum of the squares of the field strength may be scaled to read true power or the sum of the transmitted reflected powers as both values may be equated to the field strength in the line. In a modification, Figs. 3, 4 (not shown), the detector probes 3a, 4a are each replaced by an aerial thermo-couple arrangement housed in separate compartments secured to the outside of the wave-guide. The same galvanometer may be used for series or parallel connection of the detectors, Figs. 5, 6 (not shown), if the detectors and the galvanometer have the same individual resistance. Specification 591,210 is referred to.

Filed: 1943-10-13
Abstract: 581,784. Ratchet gearing. BENDIX AVIATION CORPORATION. Oct. 13, 1943, No. 16836. Convention date, March 24. [Class 80 (iii)] [Also in Group XXXIV] A locking device for a brake that is applied by successive strokes of a hand lever comprises a pawl pivoted to a link so as to form a toggle which is arranged to be broken to disengage the pawl to release the brake by a third link acting on the pivot of the toggle. The third link may be foot-operated. Operating mechanism for a pair of parking brakes for a tank, one for each track, is shown and comprises a pair of hand levers 11 and a pair of locking devices simultaneously disengageable by a common foot member. Each hand lever 11 is pivoted on a shaft 14 and carries on a pivot 19 a pawl 18 by which it operates by successive strokes a ratchet wheel 15 also mounted on the shaft 14 and connected by a rod 17 to one of the brakes. The pawl 18 is disengaged from the wheel 15 in the initial position of the lever 11 shown, by engagement with a pin 21 on the brackets 12, 13 which carry the shaft 14. The wheel can be locked by a pawl 26 pivoted at 27 to a link 25 pivoted at 24 to the brackets and controlled by a link 32 extending from the pivot 27 to an arm 34 on a shaft 37 pivoted on the brackets and carrying a second arm 38. The pair of arms 38 for the two brakes are connected by a foot member 39. The pawl which is held in engagement with the ratchet wheel by a spring 30 forms with the link 25 a toggle which in the locking position shown is past the dead centre position and is prevented from further movement in this direction by the engagement of shoulders thereon with the upper edges of the link 25 which comprises a pair of members side by side. A slot 36 in the link 32 compensates for differences in the positions of the ratchet wheels of the two brakes. When pressure is applied to the foot member 39, the link 25 is turned counter-clockwise on its pivot 24, causing the nose of the pawl to roll on to the ratchet tooth, these being rounded to reduce the friction, until the toggle is broken and disengagement is effected, this movement being limited by engagement of the nose of the pawl with a stop 25a on the link 25. The arrangement is such that a comparatively small force is necessary to effect the disengagement of the pawl.
